Abstract (en)
[origin: EP1525942A1] The blade (16), positioned in opposition to the direction of a gas flow (20), is joined to a platform (21) on top of a base (23). It is made of a sheet bent around a vertical axle in order to create a curved front (25) and to form one lateral area serving as a suction zone (27) and an opposite side serving as a pressure area (28). Both segments (27, 28) meet at the rear forming a vertical edge (26). A vertical slot (30) is located in the rear area of the blade (16) close to the platform (21) in order to counteract the forces acting on the blade (16) when a fissure (31, 32) has occurred.
